CAUTION
Do not use the unit for special purposes, such as storing food, raising animals,
growing plants, or preserving precision devices or art objects.
It can degrade the quality of the preserved or stored objects.
Do not install where there is the danger of combustible gas leakage.
Do not install the unit near a source of heat, steam, or
fl
ammable gas.
Install the unit where drainage does not cause any trouble.
Install the indoor unit, power supply cable, transmission cable, and remote controller
cable at least 40 in. (1 m) away from a television or radio receivers. The purpose of
this is to prevent TV reception interference or radio noise.
(Even if they are installed more than 40 in. (1 m) apart, you could still receive noise
under some signal conditions.)
If children under 10 years old may approach the unit, take preventive measures so
that they cannot reach the unit.
Decide the mounting position with the customer as follows:
(1) Install the indoor unit on a place having a suf
fi
cient strength so that it withstands
against the weight of the indoor unit.
(2) The inlet and outlet ports should not be obstructed; the air should be able to blow all
over the room.
(3) Leave the space required to service the air conditioner.
(4) A place from where the air can be distributed evenly throughout the room by the unit.
(5) Install the unit where connection to the outdoor unit (or RB unit) is easy.
(6) Install the unit where the connection pipe can be easily installed.
(7) Install the unit where the drain pipe can be easily installed.
(8) Install the unit where noise and vibrations are not ampli
fi
ed.
(9) Take servicing, etc., into consideration and leave the spaces. Also install the unit
where the
fi
lter can be removed.

3.3. Installing the unit
WARNING
Install the air conditioner in a location which can withstand a load of at least 5 times
the weight of the main unit and which will not amplify sound or vibration. If the
installation location is not strong enough, the indoor unit may fall and cause injuries.
If the job is done with the panel frame only, there is a risk that the unit will come
loose. Please take care.
